A puddle in the dishwasher is a good reason to pause before starting the next load. But the first thing I’d check isn’t the pump. It’s where the water is sitting.
Water down inside the filter well, water spread across the floor of the tub, and water that returns after you use the sink tell different stories. Here’s how to sort them out before paying for a part or trying another cleaning cycle.
A little water can be normal—but the location matters
GE gives two different descriptions in its drainage guidance. For models without an Ultra Fine filter, it describes one to two cups of clean water as normal. For models with that filter, water in the sump is normal, but water covering the tub floor is not. That distinction belongs to those GE designs; it is not a universal allowance for every dishwasher.
Find your model on the door edge and compare the filter drawing with the manual. If the only water is in the recess and the machine otherwise washes normally, identification comes before intervention.
Use the timing to narrow the next step
| What you see | Where to start |
|---|---|
| A pool immediately after a completed cycle | Confirm the cycle finished; inspect the removable filter and accessible drain route. |
| The tub empties, then water returns | Note whether sink use coincides with the return. Have the shared drain connection checked. |
| The problem began after a new garbage disposal | Ask the installer to verify the dishwasher inlet plug was removed. |
| The dishwasher and sink both drain slowly | Investigate the shared plumbing before replacing an appliance component. |
There is no need to keep running the machine to collect evidence. A note from the completed cycle and ordinary sink use is enough to describe the pattern. Stop using it if water leaks, the level rises unexpectedly, or a fault message tells you to stop.
The under-sink check that is easy to overlook
Look at the visible drain hose without loosening it. A crushed section, a tight bend, or a change following plumbing work is useful information for an installer. If there is an air gap, follow its cleaning instructions. Hose height and routing come from your installation guide, not a height copied from another brand.
Do not pull a built-in dishwasher out just to inspect the hose. That introduces water and electrical connections into a job that began as an observation. Chemical drain cleaner is also the wrong shortcut: GE expressly advises against putting it in a dishwasher.
If the removable filter is dirty
Let the appliance cool and disconnect power before reaching inside. Remove only the assembly the manual identifies as user-removable. Rinse away food, gently clean as directed, and check that every section locks back into place. Our filter guide explains why a clean but poorly seated filter is an unfinished job.
A clean filter does not rule out an installation problem. If a permitted drain attempt still leaves an abnormal pool, or water returns while the appliance is idle, move to support rather than repeating filter cleaning.
GE GDT650SYVFS: a model-specific drainage route
Map the water before choosing a task
Record the location. A small amount below the tub floor is different from a pool spread across the tub.
Record whether the cycle finished. Use the model’s drain and installation instructions before considering parts.
Record whether sink use preceded the return. Include sink drainage and recent disposer work in the support report.
Open a short observation record
Describe what you can see; these notes do not diagnose the pump.

Stop route: “LEAK DETECTED” on this GE model calls for service, not another comparison cycle.
US model; manual-based example, not a reported repair. The model’s official owner page links manual 49-4000283 Rev 8, April 2026. Printed pages 20 and 23 cover maintenance and drainage. Match your appliance label and manual revision first.
| Situation | Model-specific next check |
|---|---|
| Standing water | Page 23 identifies a clogged air gap or missing high drain loop/air gap. Check the installation instructions; do not improvise a hose height. |
| Water will not pump out | Page 23 directs attention to the air gap, disposer, and sink drain. A slow sink may need a plumber. |
| Grit accompanies the problem | Page 20 describes accessible Ultra-Fine/Fine filters. Follow that assembly’s cleaning and refitting directions. |
| “LEAK DETECTED” appears | Page 23 directs the owner to service. Stop repeated test cycles. |
Illustrative decision: if the sink also drains slowly, report both symptoms before assuming a failed dishwasher pump. If the plumbing checks and permitted maintenance do not resolve the issue, give service the model, error, and water timing.

A service report you can fill in
Copy this into a message or take it to the service desk. Use what you have already observed; do not repeat cycles to reproduce a leak or fault.
My dishwasher model is ______; the displayed message is ______ (or none). The last cycle was completed / interrupted / uncertain. Water was inside the filter well / across the tub floor / elsewhere: ______. It remained after the cycle / returned later; sink use before the return was yes / no / unknown. The sink drains normally / slowly / not checked. Recent disposal or installation work: ______. Owner maintenance already completed under the manual: ______.
“Unknown” is useful information. Leave uncertain details open instead of declaring a failed pump. For the GE example above, “LEAK DETECTED” takes the service route immediately.
If drainage is normal and smell is the only complaint, switch to the odor guide. Cleaning and drainage sometimes overlap, but they are not interchangeable diagnoses.
